Marketers have the major responsibility for identifying significant marketplace changes using a marketing information system and a marketing intelligence system. Which of the following is an incorrect statement?
a. The order to payment cycle is used internally for tracking results and includes orders, invoices, back-orders and stock items, shipping and billing documents.
b. Sales information that is timely is critical and for firms like Walmart results in a differential advantage for stocking, just in time inventory, and other logistics decision-making
c. Databases, data warehousing, and data mining can garner fresh insights into neglected customer segments, trends, loyalty, and other information.
d. Marketing intelligence can involve many sources including sales force, distributors, external experts, internal networks, customer advisory panel, government data, information from outside research firms, and searching the internet.
e. Overhead costs incurred with market research and intelligence should be eliminated and not replaced, because the activities are not directly related to selling goods or services.

E. Overhead costs incurred with market research and intelligence should be eliminated and not replaced, because the activities are not directly related to selling goods or services.

Explanation:

Marketers have the major responsibility for identifying significant marketplace changes using a marketing information system and a marketing intelligence system. Overhead costs incurred with market research and intelligence should be eliminated and not replaced, because the activities are not directly related to selling goods or services is an incorrect statement. Overhead costs known as manufacturing overhead, factory burden, factory overhead or production overhead is the combination of all the manufacturing costs such as electricity cost, factory supplies, factory labor (not direct one), rent, insurance, heating, water and all other energy related costs, salaries, cleaning, oiling, greasing, servicing and repairs etc. It is the some of all of the indirect material, labor and any other cost which can not be identified easily with the products and units produced in the manufacturing plant which are assigned to the every produced unit on equal basis. Overhead costs incurred with market research and intelligence should not be eliminated and replaced, because the activities are very much directly related to selling goods or services.

sound is invisible, but sometimes we can feel it. when a kettle-drum is thumped with a stick that time the tight drum skin moving up and down very quickly for some time and then it pumped sound waves into the air. loudspeakers also work in a similar manner.

components of a speaker:

electromagnet

in order to translate an electrical signal into an audible sound, an electromagnet is used in looudspeakers

  suspension

suspension is used to   center the voice coil in the gap of the magnet and it exerts a restoring force to keep it there. suspension is used to limits the maximum mechanical excursion of the diaphragm and voice coil.

voice coil

voice coil is a coil of wire which is attached to the apex of a loudspeaker cone. it provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.

cone

in a   loudspeaker, a   thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap due to which it vibrates   and produced sound. it is known as diaphragm and it can also be called a cone, though not all speaker diaphragms are cone-shaped.

surround

surround is also known as front suspension. surround is used to join the cone to the chassis. together with the suspension it controls the cone excursion, and it is also used to   determine how energy which is   travelling through the cone is absorbed, and how the speaker limits when it reaches the ends of its travel.

dustcap

dustcap is used to protect the voice coil from dust and dirt. it is a part of the cone.

how speaker work

the outer part of the cone is fastened to the outer part of the loudspeaker's circular metal rim. the inner part is fixed to   voice coil that sits just in front of a permanent magnet . when loudspeaker is hooked up to a stereo, electrical signals feed through the speaker cables into the coil. it will convert the coil into an electromagnet magnet . when electricity flows back and forth in the cables, the electromagnet either repels or attract the permanent magnet. this moves the coil back and forth, and it pull and push the loudspeaker cone. like a drum skin vibrating back and forth, the moving cone pumps sounds out into the air.in this way loudspeakers works.
